I was doing some research when I came across this dead link with Google:

:(
I clicked the "View as HTML" link and got this:

I would like to see what happens when you use this as electrodes with a couple of KV! (Static is high voltage with... 0 amps)
BTW: heating the water/electrolyte does mean supplying some of the reaction energy as heat. (google: high heat electrolysis)
There is plenty of waste heat from an ICE...
